Hi,
On a Luminous cluster having some misplaced and degraded objects after
outage :
health: HEALTH_WARN
22100/2496241 objects misplaced (0.885%)
Degraded data redundancy: 964/2496241 objects degraded
(0.039%), 3 p
gs degraded
I can that Ceph gives priority on replacing objects instead of repairing
degraded ones.
Number of misplaced objects is decreasing, while number of degraded
objects does not decrease.
Is it expected ?
In general it’s not, but as you only have 3 degraded PGs and appear to have several more misplaced ones, you are a lot more likely to have reached some kind of edge condition where the OSD-local scheduling decisions aren’t working out quite right at the global level. Or it may be that there’s a CRUSH error and it can’t figure out where to place new replicas of the PGs at all.
Can you provide a full osd and pg dump in addition to all of “ceph -s”?
Florent
